The egg, 3 larval instars and pupa of Enytus sp. a univoltine, primary endoparasitoid on the feeding larva of the jarrah leafminer Perthida glyphopa Common, are figured and its life history described. Single eggs laid in July and August hatch rapidly, but the caudate larva develops slowly, allowing the host to complete feeding, construct its cell and aestivate in the soil. The parasitoid's final instar larva destroys the host in March, April or May of the following year, spins a cocoon and pupates in the cell where ecdysis occurs. The species was found most frequently in areas of low host density.
